FN 545® Tactical

Available for commercial, law enforcement, and military.

MSRP: $1,139.00

Leave nothing to chance with 18+1 rounds, setting a new standard capacity in .45 ACP. Suppressor-ready, with a threaded barrel and co-witness tritium night sights, this industry-first pistol is upgraded with the proven ergonomics of the FN 509® Tactical. Shooters can mount their favorite red dot optic in minutes, adding pinpoint control on command. Complete with the high-endurance striker and crisp, approximately 6lb. trigger pull, the FN 545 Tactical is what other big bore pistols want to be when they grow up.
